Timothy Olyphant -- "The League": This little FX gem has a fantastic history of guest stars. Jeff Goldblum as Nick Kroll's father may be the best bit of father/son casting I've ever seen. But when ol' Raylan Givens showed up as a laid back, surfer-brah sushi chef, it was pure delight. "Arigatou, Racists" may be my favorite catchphrase of all time.

Carrie Preston -- "The Good Wife": We talk a lot about Elsbeth Tascioni on this site. It's because she's one of the best TV characters on a show you're not paying nearly enough attention to. I don't know if Preston's character is too quirky to hold down her own show, but she's spin-off material if ever I saw it. Preston is fine and dandy on "True Blood" but she's in another class altogether here.

Andrew Rannells -- "Girls": Rannells is, without a doubt, a talented fellow. You need only look at his impressive run in "Book Of Mormon" too see it for yourself. But the hacky writing on "The New Normal" was excruciatingly hard to watch. Rannells was much better served by Lena Dunham's scripts during his guest arc on "Girls." As was often the case this season on that show, the boys got the best material.

Allison Williams -- "The Mindy Project": Speaking of "Girls," I had been having a hard time divorcing Allison Williams from her dreadful, hateful character Marnie. Say what you will about Hannah, I think Marnie is the real villain of that show. But Williams was delightfully dry as Chris Messina's brief flame "Eye Patch" on "The Mindy Project."

Dermot Mulroney -- "New Girl": I tried watching "Enlightened." I really did. In my opinion, the only saving grace in the first season was Luke Wilson. He was pretty much replaced in the second season by Dermot Mulroney who was...well...boring. Thank goodness he'll be back on "New Girl" this April. Fingers crossed "True American" won't be far behind.

Walton Goggins -- "Sons Of Anarchy": This right here made the whole sh*tshow that was Season 5 of "Sons Of Anarchy" worth it. Maybe the best thing I've seen all year.

Mark Duplass -- "The Mindy Project": Everything Duplass touches turns to gold. And as much as I love his bro-y character on "The League," his smarmy midwife Brendan Deslaurier his comedic gold. I hope he and his brother Jay stick around for the entirety of "The Mindy Project"'s run.

Matthew Perry -- "The Good Wife": Matthew Perry has been punching below his weight all season on NBC's "Go On." If the promos for next week's "The Good Wife" are any indication, however, he'll be back in fine form. It's not quite Sorkin, but it's close.

Nothing will top Venus, but I really live Carrie Preston on The Good Wife. She also pops up on her husband's show

Carrie Preston and Michael Emerson are such an adorkable couple of fruit files, I'd watch almost everything they're in, all the way back to Straight-Jacket.

Bodhi

My husband doesn't watch Justified, so he didn't understand why I loved Timothy's appearance on the League. . I don't watch SOA but Boyd in drag is something I think I have to see

That is a ridiculous tuxedo, and yet somehow Perry is making it work.

quadrigae

That's not a tuxedo, it's a tail coat.

I stand sartorially corrected. I know not all the vernacular for men's formal options. And perhaps it was a white-tie event and necessitated such formality, though it still seems more suited (no pun intended) for someone about to sit down to a grand piano.

Allison Williams also popped up in the third season of The League as Mark Duplass's lineup-tinkering girlfriend. Mindy Project/The League synergy!

Would also add: Neil Patrick Harris in Adventure Time and Megan Mullally in Parks and Rec.

Megan Mullally as multiple characters in Bob's Burgers. Her songs are awesome.

Emma

Yes! Did you enjoy Donald Glover's turn as Marshall Lee, as well? I thought he was perfect!

Lovely Bones

Really, one could say almost any of the guests that AT has featured, if not any and all of them. George Takei, Clancy Brown, Mark Hamill, Cloris Leachman. . Matthew Broderick was one of the only guest actors, if not the only, to be kind of wasted.

Tinkerville

Love, love, loved Donald Glover as Lee! Great voice casting there.

AvaLehra

Adventure Time AND Regular Show, FTW.

Lovely Bones

Drugs have absolutely nothing to do with the series' appeal, JoRo, but if that's where the discussion's going to start, I don't want to be a part of it. I can understand not being interested in the show, though. And to be fair, I'm barely an adult, by physical, official terms. And Tinkerville, you aren't exactly helping the image of the show or its fans that way. Sorry for being the overly serious guy, but I really love the show, and the drug thing constantly gets used by people that don't understand the show and want to bash it. It dismisses the fans as shallow.

You are correct, Megan Mullally is freaking glorious when's she's on P&R! When I see Tammy 2 I know it's going to be an amazing episodeand all I can think of is Ron missing his eyebrows & stache and then having dreadlocks.

JoannaRobinson

Are you one of those adults who watches Adventure Time? How do you do that? Is the answer An Elephant F*ck Ton Of Drugs?

Steph

It's really funny and packs a lot into ten minutes. It's better than every show on this list too, it's not even close.

Personal preference. I understand that. But just because a show is a cartoon and lots of kids watch it, that does not make it juvenile.

Emma

Doctor Who is a children's show as well, you know. Just sayin'.

Fabius_Maximus

Bad comparison. Doctor who is a family show.

Hazel Dean

Semantics. Those words ("family" and "children") can be and are often used interchangeably. If anything, Adventure Time can at times be for more mature audiences than Doctor Who, and deals with more adult, darker themes. Have you ever even watched the show?

Fabius_Maximus

No. I find the art style repulsive.

But if you and Jessica say it deals with these adult issues, then it's not a show for kids alone, either.

Considering Adventure Time covers more emotional terrain than a lot of shows; such as abandonment, mental illness, acceptance, queer issues, suicide, etc., it can hardly be considered just a show for kids. Anyone with ability to see beyond the absurd fantasy fist-bumping fun will be rewarded with rich characters and story-telling.

I am indeed. Join us! Ours is the psychedelic way of bountiful liquor, special brownies, and endless iterations of "what in the holy fuck did I just watch." It is not a path for the faint of heart, so choose yours wisely.
